INVIENT EDWARD BEETLESTONE, OF WEST SMETHWIOK, ENGLAND.

GLASS-ROLLING MACHINERY.

Specification of Letters Patent.

Patented April 17, 1906.

Application filed October 10, 1905- Serial No. 282,180.

' ing at the Glass Works, West Smethwick, in

the county of Stafford, England, have invented new and usefulImprovements Relating to Glass-Rolling Machinery, of which the followingis a specification.

This invention relates to glass-rolling machines of the type well knownas the Chance double-roll-machine, in which one or more pairs of rollsare employed in combination with inclined plates arranged for thesupport of the glass.

The invention comprises the construction and arrangement of the teemingor like plate (from which the glass is fed between the rolls) in such amanner that the respective surfaces or tablets of the same may veryreadily and conveniently be successively brought into and placed out ofoperation, whereby they are maintained in an efiective condition and thelife of the plate increased.

Referring to the accompanying sheet of explanatory drawings, Figure 1 isa side elevation, and Fig. 2 a plan, of a teeming-plate constructed andarranged in accordance with this invention and shown in conjunction witha glass-rolling machine of the type referred to.

The same reference-letters in the two views indicate the same parts.

In one manner of carrying the invention into effect the plate, as a, ismade of a triangular, transverse, or sectional form and is mounted ontrunnions b, enabling it to be rotated. The trunnions may be fitted withconnections for the circulation of water through the interior of theplate. The trun- ,nions are preferably mounted in lever-like supports 0,adapted to be so rocked or moved about their pivot-shaft d, by means ofan opcrating-lever, as e, as to bring the forward end of the plate ainto its service position in contact with the lower roll, as f, or towithdraw it from such position, as shown by dotted lines at Fig. 1, forthe rotation of the plate a to put one of the surfaces or tablets out ofaction and to replace same with the succeeding surface or tablet. Theteemingplate is retained in its operative positions by means of suitablestops, such as g, fixed on the trunnions and engagingconveniently-arranged abutments or catch-pieces h upon the framing orhousings i, of the rolls and also by an adjustable stop j, which isengaged by the operating-lever e, as illustrated.

With a triangular plate, as aforesaid, each surface is in action or isin use as a supporting and teeming surface for the glass for one periodand is out of service and subjected to atmospheric cooling for twoperiods, for after a given period of service with one surface or tabletthe two remaining surfaces or tablets are brought successively into andput out of action before the first-named surface is again required.

The rotatable plate may be modified in its form and in its arrangementto meet varying requirements. I

Having thus described my invention, what I claim as new, and desire tosecure by Letter Patent, is-

1. In glass-rolling machinery, the combination with the rolls of acontinuous series of glass-supporting tablets rigidly united at theirabutting edges and forming a rotatable teeming-plate, and rocking orlever-like supports for the said plate, substantially as de scribed.

2. In glass-rolling machinery, means for feeding the glass between therolls consisting of a rotatable triangular teeming-plate, the fiatsurfaces of which are adapted to receive the glass.

3. In glass-rolling machinery, the combination with the rolls of acontinuous series of glass-supporting tablets forming a triangularteeming-plate, trunnions carrying the said plate, lever-like supportsfor the said trunnions, a pivot-shaft for the said supports, and anoperating-lever secured to the said shaft, substantially as set forth.

4. In glass-rolling. machinery, the combination with the rolls of acontinuous series of glass-supporting tablets forming a triangularteeming-plate, trunnions carrying the said plate, lever-like supportsfor the said trunnions, a pivot-shaft for the said supports, anoperating-lever secured to the said shaft, and means retaining therespective tablets by turns in the operative position, substantially asset forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
